I made a little research about your usb stick and it must be D-Link DWA-182 rev C1 (rev C - not rev A).
Rev C needs the realtec driver rtl8812AU.
I found the website of Dlink and it seems that they provide a linux driver (!).
See here:
http://support.dlink.com/ProductInfo.aspx?m=DWA-182I have not tried it before, but I suggest you do the following.
Unplug the usb stick.
Download from here the driver:
https://www.dropbox.com/s/2nj5vthwiqri4 ... 411.tar.gzIt is a compressed file named "RTL8812AU_linux_v4.3.2_11100.20140411.tar.gz". I will be downloaded in your "Downloads" folder. Go there, right-click it and select extract here. A folder named "RTL8812AU_linux_v4.3.2_11100.20140411" will be created.
Inside this folder you will find a file named "install.sh". Right-click it, go to properties > permissions tab and tick the box that says "allow executing file as program".
Close and exit.
Then open terminal (Ctrl+Alt+T) and run the following commands:
cd /home/$USER/Downloads/RTL8812AU_linux_v4.3.2_11100.20140411
sudo ./install.sh
If you are asked for your password, just type it (even if you don't actually see it being typed) and press <enter>
If all goes well, the driver should be installed.
If you are asked to answer "yes" during the process, type "y" (without the quotes) and press <enter>.
After the installation is completed, plug your USB dongle, wait 5-6 seconds and see if you can find wireless networks.
If you get any error messages, post them here.
